AOA Ramp Lighting

Customer: Port of Seattle

Project Location:Seattle, Washington

The existing aircraft parking ramp lighting at the Seattle-Tacoma International Airport’s North and South Satellites, Concourses B, C & D, and Gate A-14 was found to be inadequate. The Port wished to replace the entire existing pole mounted light fixtures at the North and South Satellites, and Concourses B, D and C (with the exception of 14 locations). The basic criteria required for the ramp lighting retrofit was to match the higher light levels of Concourse A as well as utilize the same light fixture and lamp type used at Concourse A. The design effort also included investigation of several Hardstand areas which were individually analyzed by Harris Group and were found to have acceptable light levels.

The Challenge

The requirements for light levels and glare levels were not clearly defined prior to the start of design.

Construction associated with the retrofit of this ramp lighting could not impact the airline operations in any way. Significant operations occurred during non-daylight hours as well as the individual ramp lights were not separated by gate, rather they supported (contributed to) multiple gates.

The Solution

Harris Group has extensive experience and expertise with the industry leading lighting analysis and design software called AGI-32. While developing an AGI-32 lighting model of the retrofit areas, Harris Group concurrently developed a model of the existing concourse A lighting. The concourse A model results were used to establish and document the criteria for the areas requiring retrofit. Harris Group performed a significant amount of research on the Federal Aviation Administration (FAA) requirements to ensure the design not only met the Concourse A Baseline criteria, but also all applicable FAA codes and standards.

Extensive field investigation and documentation of the lighting was performed. A significant amount of coordination was performed with the operations group. The design documents included a detailed construction sequence for each concourse and satellite.

The Benefits

The contractor was able to complete the installation in significantly less time than they initially planned. The reduction in construction schedule was attributed in large part to the quality of the design documents. The project experienced a reduction in potential impact to aircraft operations which was a direct result of the significant reduction in installation time and smooth work flow. In appreciation, the Port sent Harris Group a letter of gratitude.
